Application filed February T 0 all whom it may concern:

Be it known that I, GUST HEGLUND, a citizen of the United States,residing at Andover, in the county of Anoka and State of Minnesota, haveinvented certain new and useful Improvements in Snowplows, of which thefollowing is a specification.

My invention relates to snow plows, and an object in general is toprovide a device of this character which is applicable to a motorpropelled vehicle for the purpose of removing snow from roads by meansoperating to throw the snow to the sides of the road whereby the roadwayis cleared. Special objects of my invention are to provide means whichwill throw the snow laterally of the roadway with a great deal of forceso that the snow will not be liable to return into the roadway, toprovide means which will permit the inclination of the discharge spoutto be readily varied, and to provide means which will operate to breakup hard snow before it reaches a fan casing from which it is dischargedlaterally.

The full objects and advantages of my invention will appear inconnection with the detailed description, and the novel features of myinventive idea will be particularly pointed out in the claims.

In the accompanying drawings which illustrate the application of myinvention in one form,

Fig. 1 is a top plan view of my snow plow. Fig. 2 is a view in centrallongitudinal section. Fig. 3 is a view in section on the line 3-3 ofFig. 2. Fig. 4 is a View in section on the line 44 of Fig. 2. Fig. 5 isa fragmentary view in section on the line As shown in the drawings, Iprovide a wheeled frame 10 upon which a drive shaft 12 is rotatablymounted. This shaft may be driven by any suitable motor mounted on theframe and said shaft extends centrally through a circular fan casingcontaining a number of fan blades 14 secured to the shaft. The rear wallof the fan casing consists of a disk 16 which is secured to the frame 10by braces 18 and angle members 20. The front wall of the fan casingconsists of a disk 22 which is secured to a front casing 24 by braces 26and angle members 28 and 36. The peripheral wall of the fan casingconsists of two semi-circular members 32 and 34 held together by curvedplates 36 secured 4, 1924. Serial No. 690,432.

to the semi-circular members adjacent their abutting ends. The marginalportions of these two semi-circular members have secured thereto pairsof inwardly projecting flanges 38 and 40 which respectively engage themargins of the disks 16 and 22 on their inner and outer surfaces. Inthis manner the members 32 and 34 are frictionally held in place so thatthey may be turned to vary the inclination of a discharge spout 42 whichis secured to the upper peripheral member 32. The forward end of thedrive shaft 12 extends centrally through the fan casing and into thefront casing 24 and has secured thereto cutting blades 44 positionedwithin the front casing 24. The shaft 12 is supported adjacent thecutting blades by a bearing 46 secured to a bar 48 passing transverselythrough the walls of the casing 24 and having its ends secured to arms50 extending rcarwardly from the front portion of the casing 24. The bar48 is additionally held by braces 52 extending down from the top of thecasing 24 and secured to said bar. Vertical bars 54 depending from theframe 10 secure two channel bars 56 in place, these channel barsprojecting hori- Zontally and forwardly beyond the fan casing. Braces 58connect the front disk member 22 with the channel bars 56. A plate 60 issecured to these channel bars and to the bottom portion of the casing 28which is extended to produce av scooplike member 62 for scooping up thesnow. The front disk member 22 is partly cut out to produce an opening64 for passage of snow from the cutting blade chamber into the fanchamber, and it will be apparent from Figs. 1 and 2 that the walls ofthe cutting blade chamber converge rearwardly toward the opening 64 inthe manner of a hopper so that the snow is put under pressure as itpasses into the fan chamber.

The operation and advantages of my invention will now be obvious. Theprovision of the cutting blades 44 makes it a much easier matter todrive the snow plow through snow drifts since these blades cut up thecaked or hardened snow. On account of the fact that the snow is fedthrough a constricted passageway into the fan chamber it will bedelivered from the discharge spout 42 with considerable force so that itis carried away from the roadway a sufficient distance not to obstructthe roadway and without liability of falling back again into the clearedroadway. As previously described, the peripheral portion of the fancasing carrying the discharge spout may be rotated to change theinclination of the latter whereby the snow may be delivered over highdrifts.

I claim:

1. A snow plow comprising a wheeled frame, a fan casing secured to thefront of said frame, a discharge spout carried by the peripheral portionof said fan casing, means which permits rotative movement of saidperipheral portion with relation to the remainder of said casing wherebythe inclination of said spout may be varied, a drive shaft supported bysaid frame and extending centrally through said casing, and fan bladessecured to said shaft.

2. A snow plow comprising a wheeled frame, a fan casing secured to thefront of said frame, a discharge spout carried by the peripheral portionof said fan casing, means which permits rotative movement of saidperipheral portion with relation to the re mainder of said casingwhereby the inclination of said spout maybe varied, a cutting bladecasing attached in front of said fan casing, said cutting blade casingbeing open atits front and communicating with said fan casing through arestricted opening, a drive shaft supported by saidframe, and extendingcentrally through said fan casing and into said cutting blade casing,fan

blades secured to said shaft, and cutting blades secured to said shaft.

In testimony whereof I hereunto aflix my signature.

GUST HEGLUND.
